How are the cells of a person with Down syndrome different from those of a person without Down syndrome?
In Down syndrome, a person's cells have an extra copy of chromosome 21. In other words, instead of a pair of chromosomes, a person with Down syndrome has three of that chromosome. Down syndrome most often occurs when chromosomes fail to separate properly during meiosis. People with down syndrome have a degree of mental retardation. Heart defects are also common, but can be treated.

Klinefelter syndrome can result from?
Klinefelter syndrome can result from errors in cell division of sperm or egg cells. With this syndrome, each of the cells of the person affected will have an extra X chromosome.
Why is it Mosaic?
It is called a mosaic when an individual has different genome on different cells. For example a person can have trisomy 21 (down syndrome) in some specific tissue and be completely normal on other tissue.
How do the cells of people with down syndrom differ from those of others?
People with Down syndrome have an extra copy of chromosome 21 in their cells, leading to 47 chromosomes instead of the usual 46. This genetic condition can result in various physical and cognitive differences, such as distinctive facial features and intellectual disabilities, compared to individuals without Down syndrome.
What condition occurs when a person's cells have an extra copy of chromosome 21?
down syndrome !! hope this helps
How many chromosomes are found in a nerve cell of a down syndrome person?
The same as all of the other cells.
What is bare lymphocyte syndrome?
Bare lymphocyte syndrome. In this form of SCID, the white blood cells (lymphocytes) in the baby's blood are missing certain proteins. Without these proteins, the lymphocytes cannot activate the T cells in the immune system.
What type of Down syndrome is 'Mosaic'?
its where some cells are "down syndrome" cells and some are "typical" cells. meaning some cells have three sets of the 21st chromosome and some have the normal 2 sets.
How is Turners Syndrome transmitted?
Turner syndrome is caused by a missing or incomplete X chromosome in females. It is typically not inherited, but rather occurs as a random event during the formation of reproductive cells in one of the parents. It is not passed down from parent to child.
What are the similarities and differences between people with Down syndrome and people without this disability?
People with down syndrome has an extra chromosome in the 21st pair. The normal amount of chromosomes is 56 single chromosomes (23 pairs). A person with down syndrome has 57 chromosomes. Therefore, they look and act more different than people without the disorder. Instead of looking like their parents, people with down syndrome look more like other people who has down syndrome.
